### 1/5 — 使えなくなった

*2026-07-15*

前バージョンは気に入って使っていたが改悪されてリリース
入力したものが保存できないし、文字も見えにくい
コレって何に使えるの？

### 5/5 — 使えない

*2026-06-24*

バクなのか、画面おかしくて、使えない。

**Developer response:** ご不便をおかけして申し訳ありません。
最新バージョン（10.1.7）でこの問題は修正されています。
お手数ですが、最新版にアップデートしてお試しください。
今後ともよろしくお願いいたします。

### 3/5 — タイムロス

*2026-06-22*

他の日にちにコピーする時に画面が切り替わる時間が無駄。

### 1/5 — 使えない

*2026-06-17*

何故かイベントを書き込んでも保存できない。簡単に書き込みできないしとても見づらい画面で使う気にならない。前のハチliteが断然使い易いのですぐ削除した。

### 3/5 — アップデートしたら

*2026-06-14*

新しい予定を保存出来ないが。入力のミスなら指摘して欲しい。

### 5/5 — 見やすくて良い

*2026-06-13*

無料だけど、見やすくて良い。広告が入るが特に気にならない。

### 4/5 — 家族での共有カレンダーアプリではピカイチ

*2026-06-05*

女房と共有で利用していますが痒いとこよりに手が届く感が結構あり重宝しています。例えば利用者別に色分けされる、複数日にコピーできるアラームも複数設定できるなどなど。もしこれが無くなったら非常に困ります。

### 4/5 — 多少クセはありますが

*2026-06-02*

普通に使いやすいと思います。欲を言えば、次の月に移る時、もう少し操作性が良ければ。

### 2/5 — まだ慣れません。

*2026-05-27*

見た目が今までのレイアウトに慣れているせいか、色のせいかわからないですが、全体的に見づらい感じがして、前の物を見てしまってます。

### 1/5 — ハチ2Liteが好きだった

*2026-04-21*

きっと色々できるようになって進化してると思うんですが、すごく使いづらいですーーー
前のハチ2Liteが最高に使いやすかったので残念です。
